An experimental investigation of flow behavior behind a moving circular cylinder was carried out in an open channel. The cylinder was mounted on a platform and extended to submerge in the water. The platform was rested on two ball-bearing-filled tracks which were designed to reduce the friction between the platform and the tracks. The cylinder was maintained perpendicular to the platform. The platform was free to move in a horizontal plane. The flow fields behind the suspended cylinder were captured using the technique of Particle Image Velocimetry (PIV) and the trajectory of the cylinder was captured using a camera operated in video mode (60 frames per second). Instantaneous flow patterns and orbital responses of the moving cylinder were analyzed and the findings were presented herein.
